Measles

A Comprehensive Clinical & Nursing Guide

Definition

Measles is an acute, highly contagious viral illness caused by the Measles virus (genus Morbillivirus, family Paramyxoviridae). It presents with fever, cough, coryza, conjunctivitis, Koplik spots, and a maculopapular rash that spreads from the face downward.

Causative Agent

Measles virus – an RNA virus belonging to the Paramyxovirus group.

Risk Factors

• Age: Common in children under 5 years, but can affect any age without immunity.
• Sex: Equal incidence in both sexes.
• Immunity:
  • Single natural infection gives lifelong immunity.
  • Second attacks are rare.
  • Unvaccinated individuals at highest risk.
• Malnutrition: Especially Vitamin A deficiency increases severity.
• Poor living conditions: Overcrowding, poor ventilation.

💡 Global Note: Measles remains a leading cause of vaccine-preventable death in children worldwide, especially where vaccination rates are low.

Source of Infection

Infected human is the only reservoir.

Virus present in:

• Nasal secretions
• Throat secretions
• Respiratory droplets

Mode of Transmission

Highly contagious. Spread by:

• Droplet infection
• Airborne droplet nuclei
• Direct contact with respiratory secretions

Infectious period: 4 days before rash → 4 days after rash.
Maximum infectivity just before the rash appears.

Incubation Period

10–12 days (range: 7–14 days).
Prodromal symptoms appear before rash.

Clinical Manifestations

1. Prodromal Stage (Catarrhal Stage)

• High fever (100–103°F and rising)
• The 3 C’s:
  • Cough
  • Coryza (runny nose)
  • Conjunctivitis
• Watery eyes, photophobia
• Hoarseness of voice
• Koplik spots:
  • Small bluish-white spots on buccal mucosa
  • Seen 1–2 days before rash
  • Pathognomonic sign

2. Rash Stage (Exanthem Stage)

• Rash begins on face and behind ears, then spreads downward to trunk and limbs.
• Reddish, maculopapular, blanching initially.
• Lasts 5–6 days.
• Followed by brownish discoloration and fine desquamation.

3. Recovery Stage

• Fever subsides gradually.
• Rash fades in the same order it appeared.

Diagnostic Evaluation

• Clinical diagnosis is usually sufficient (Koplik spots + rash).
• Giemsa stain: Shows multinucleated giant cells.
• Immunofluorescence: Detects viral antigens in tissue.
• ELISA (IgM):
  • Confirms acute infection
  • CSF IgM used in measles encephalitis
• RT-PCR: Highly sensitive, detects viral RNA.

Complications

Common

• Otitis media
• Bronchopneumonia
• Acute gastroenteritis
• Laryngotracheobronchitis (croup)

Serious

• Acute encephalitis
• Febrile seizures
• Conjunctivitis → corneal ulcer, blindness

Long-term

• SSPE (Subacute Sclerosing Panencephalitis) – fatal, occurs years after infection
• Immunosuppression leading to secondary infections

Management

General

• Strict bed rest in a quiet, darkened room.
• Ensure good ventilation.
• Encourage plenty of fluids (water, juices, ORS, milk).
• Provide soft, nutritious, high-calorie diet.
• Maintain hygiene and comfort.

Medications

• Antipyretics: Paracetamol for fever.
• Antibiotics: Only if bacterial infection suspected (e.g., pneumonia, otitis media).
• Vitamin A Supplementation:
  • Reduces severity & risk of blindness
  • 1 lakh IU (6–11 months) or 2 lakh IU (>1 year), given on 2 consecutive days.

Isolation

• Isolate the patient until 4 days after rash onset.
• Avoid contact with unimmunized persons.

Prevention

Active Immunization

• Measles vaccine / MMR vaccine
• 0.5 mL subcutaneous
• Given at 9 months, 16–24 months, and 5 years (as per local schedule).

Passive Immunization

Human immunoglobulin for:

• Malnourished children
• Immunocompromised individuals
• Infants <6 months
• Pregnant women exposed to measles

🌍 Herd Immunity: ≥95% two-dose MMR coverage is needed to stop community transmission.

Nursing Management

1. Assessment
   • Monitor: Temperature, respiratory rate, hydration, rash, eye/ear symptoms, neurological signs
   • Check immunization history.
2. Infection Control
   • Airborne + droplet precautions
   • Well-ventilated, separate room
   • Caregivers must be immune
   • Use masks, gloves; practice hand hygiene
3. Comfort Measures
   • Tepid sponging for fever
   • Darkened room for photophobia
   • Clean eyes with warm water
   • Petroleum jelly for dry lips
4. Hydration & Nutrition
   • Encourage frequent fluids
   • Soft, easy-to-digest foods
   • Monitor intake/output
5. Eye Care
   • Prevent eye rubbing
   • Watch for ulceration; refer promptly
6. Skin Care
   • Keep skin clean and dry
   • Trim nails to prevent scratching
   • Use soothing lotions if needed
7. Medication Administration
   • Give antipyretics as ordered
   • Administer Vitamin A
   • Antibiotics only when prescribed
8. Prevention of Complications
   • Monitor for: breathing difficulty, persistent fever, ear discharge, drowsiness, seizures
9. Health Education

Assessment on Sexually Transmitted Disease

Assessment of Sexually Transmitted Infections (STIs/STDs)

Sexually transmitted infections (STIs), also known as sexually transmitted diseases (STDs), are infections transmitted predominantly through sexual contact (vaginal, anal, and oral intercourse). Certain STIs may also be transmitted via blood, shared needles, or from mother to child. Etiological agents include bacteria, viruses, parasites, protozoa, and rarely fungi. Manifestations may involve the genitals, urethra, anus, rectum, pharynx, conjunctiva, or skin; many infections remain asymptomatic for extended periods.

A systematic, non-judgmental, and patient-centered approach is essential when assessing individuals for possible STIs.

The assessment comprises four core components:
• Comprehensive sexual & medical history
• Physical examination
• Diagnostic investigations
• Patient education and counseling

Common Clinical Presentations

• Abnormal genital, urethral, vaginal, or rectal discharge
• Dysuria (burning or pain on urination)
• Genital sores, ulcers, vesicles, blisters, warts, or rashes
• Genital or perianal pruritus
• Lower abdominal or pelvic pain (especially in females)
• Scrotal pain, swelling, or tenderness
• Dyspareunia
• Intermenstrual or post-coital bleeding
• Enlarged/tender lymph nodes
• Pharyngeal discomfort or exudates
• Systemic symptoms (fever, rash, arthralgia)

Note: Many STIs (e.g., chlamydia, gonorrhea in women, HPV) are asymptomatic; screening is indicated in high-risk groups even without symptoms.

Comprehensive Sexual and Medical History

Key elements to cover confidentially and empathetically:

• Presenting complaint and timeline of symptoms
• Number and gender of sexual partners (past 6–12 months and lifetime)
• Types of sexual practices (oral, vaginal, anal; insertive/receptive)
• Consistency of condom/barrier use
• Symptoms or known STIs in partner(s)
• Date of last sexual contact and last unprotected exposure
• Previous STI history and treatment completion
• Drug use (especially stimulants linked to high-risk behavior)
• History of sexual assault or coercion
• Contraceptive method, last menstrual period, pregnancy history (women)
• Cervical screening and vaccination status (HPV, Hep A & B)
• Travel history and general medical/medication history

Physical Examination

General Examination

• Vital signs, weight, pallor, jaundice
• Skin and mucous membranes (rashes, lesions)
• Lymph node palpation (cervical, axillary, inguinal)
• Oral and pharyngeal inspection

Genitourinary & Anorectal Examination

• Inspection: External genitalia, urethral meatus, retraction of foreskin (males), speculum exam (females when tolerated), perianal region
• Palpation: Inguinal nodes, bimanual pelvic exam, Bartholin/Skene glands, scrotal contents, digital rectal exam if indicated

Important: Defer speculum/bimanual exam in suspected sexual assault or when severe pain/ulceration is present.

Diagnostic Investigations

• Serology: HIV Ag/Ab (4th gen), syphilis (RPR/VDRL + TPHA/FTA-ABS), hepatitis B & C
• NAAT (preferred): First-void urine or vaginal/rectal/oropharyngeal swabs for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Mycoplasma genitalium
• Lesion swabs: HSV PCR, syphilis PCR/dark-field
• Other: Wet mount, Gram stain, Pap smear/HPV co-test, pelvic ultrasound (if PID suspected)

Patient Education and Counseling

• Consistent and correct condom use (male/female condoms, dental dams)
• Reduction in number of sexual partners or mutual monogamy
• Regular STI screening, especially <25 years or with new/multiple partners
• Completion of full treatment course and abstinence until cured
• Partner notification and simultaneous treatment
• Vaccination: HPV (up to age 45 where indicated), hepatitis A & B
• Avoid vaginal douching and unnecessary antibiotics
• Offer PrEP or doxy-PEP where guidelines recommend
• Psychosocial support and referral as needed

A holistic, patient-centered approach combining accurate diagnosis, effective treatment, and compassionate education is key to reducing STI transmission and promoting sexual health.
